Expert roof inspection in Princeton, NJ. Licensed spray foam contractors with manufacturer-backed warranties and free inspections.
Whether you are buying a Princeton property, assessing storm damage, or planning long-term maintenance, our inspection reports give you the data to make confident decisions. Every component is evaluated — membrane, flashings, penetrations, drains, substrate, and insulation condition.
The buildings and homes of Princeton, NJ face unique challenges — from seasonal temperature extremes to storm exposure — that demand roofing and insulation systems built for performance, not just price. Lapolla Industries delivers roof inspection solutions using closed-cell spray polyurethane foam that outperforms conventional materials in every measurable category.
Our Princeton customers see the difference in their energy bills, their comfort levels, and the longevity of their roofing systems. Spray foam does not degrade like fiberglass, does not develop seam failures like TPO, and does not crack like built-up roofing. It is a permanent solution — and Lapolla Industries is the permanent partner Princeton property owners rely on to deliver it right.
From inspection to completion, here is how we deliver professional roof inspection results.
Before any work begins, our certified inspectors evaluate your property and provide a comprehensive assessment including current condition, repair needs, and recommended SPF solutions. You get a written estimate with no hidden fees.
Proper surface preparation is critical for spray foam adhesion and long-term performance. Our crews clean, dry, and prime all surfaces, remove debris and loose material, and ensure the substrate meets manufacturer specifications before any foam is applied.
Using precision spray equipment, our crews apply the foam in controlled passes to achieve the specified thickness and density. The closed-cell foam expands 30 to 40 times its liquid volume, conforming to every detail of the surface and creating a seamless monolithic barrier.
We finish every project with the appropriate protective coating, thorough cleanup, and a detailed walkthrough. You receive project documentation including photos, material specifications, warranty registration, and maintenance recommendations.

Our reputation is built on results. Here is what our customers have to say.
"They waterproofed our entire flat roof with a seamless elastomeric membrane. Two years later and not a single drop of water has gotten through. The application was clean and fast — three days for 8,000 square feet."
"We needed our concrete roof deck waterproofed before installing new equipment on it. The crew applied a monolithic membrane that handles foot traffic and ponding water. Two years in and zero issues. Money well spent."
"Water was coming in around our skylight every time it rained. Lapolla Industries traced it to deteriorated sealant and improper flashing. They redid everything and we have been bone dry through two heavy storm seasons now."
